Motivated by her family and driven by tenacity, Pipkin said she got serious about her health four years ago, when she quit smoking cigarettes. Last Christmas, she received a fitness tracker as a gift. Since January, she has challenged herself to surpass the amount of steps taken by her friends and family.

"It keeps me motivated. You see somebody and it's like 'oh they're getting ahead of me. I gotta go for a walk or for a bike ride.'"

Pipkin said she's constantly working on ways to up her fitness. She used to settle with one session in the gym per day, but said she continually ups the ante with added exercise daily.

"I'm also raising my granddaughter right now, so I've got to be in tip-top shape for her. Those are things that motivate me. My family."
